assume:byterecl not working in ifort 19.1?

[Froehlich__Felix]

I recently upgraded to Intel Fortran 2020 Update 1 (version 19.1.1.216) and the assume:byterecl compiler option does not seem to working properly. This is what I am testing with:

        OPEN(UNIT=datnr, FILE=TRIM(filename), ACCESS='DIRECT', FORM='UNFORMATTED', RECL=12)
        INQUIRE(UNIT=datnr, err=100, RECL=irecl)
        CLOSE(UNIT=datnr)

If assume:byterecl is not set, irecl is assigned the value of 12 (same as given in OPEN statement). Both should be in 4-byte units (longwords)).

But when assume:byterecl is set, irecl is assigned the value 3. With this compiler option, both this value and the value given in the OPTION statement should be in bytes, but apparently one of them is not.

Is there some something I am misunderstanding?

You are not misunderstanding - this is a bug introduced in 19.1. I can reproduce it.

D:\Projects>type t.f90
OPEN(UNIT=1, FILE='foo.dat', ACCESS='DIRECT', FORM='UNFORMATTED', RECL=12, status='REPLACE')
INQUIRE(UNIT=1,RECL=irecl)
print *, irecl
CLOSE(UNIT=1)
end

At least the file is created with the correct record length, based on an additional test I did. It's just INQUIRE that gets it wrong.

[Froehlich__Felix]

Thanks for confirming, Steve. So what now? How should I report this so that it gets fixed asap?

[Steve_Lionel]

Use the Online Service Center if you have current product support.

[Froehlich__Felix]

I do have current product support, from my understanding I am even eligible for "Priority Support". But the Intel website is having me run around in circles. I am unable to actually submit a ticket or contact support. Either I am again "misunderstanding" or the website has a bug as well.

The closest I have gotten is this page: https://www.intel.com/content/www/us/en/develop/support/priority-support.html but that just sends me back to the Online Service Center? I have been signed in all the time, mind you.

Is there perhaps a more direct link to the page where you can submit a ticket?

[Steve_Lionel]

The link I provided is the page where one submits a ticket.

Click that Request Support button. What are you seeing?

[Froehlich__Felix]

Before I can click that Request Support button, the page always redirects me to a different page shown below. I have tried different browsers as well, I always get redirected and am unable to click on that button. I have also tried both being logged in and not being logged in, always getting the same result.

When I follow the links on this page, I get to this page:

Here, clicking on "Online Service Center" leads me back to the beginning. Clicking on "How to submit a request" displays a login page (even when I am already logged in), where a successful login just shows me the login page again.

[Steve_Lionel]

Sorry to hear that. I will report this for you (done: 04675699), and also see if I can get someone to look into the issue you're having with the support pages. I had hoped that one of the Intel support folk would see this and jump in, but...  Some days I feel that I didn't really retire, but am not being paid!

[Froehlich__Felix]

Thanks so much for your help, Steve.

[Steve_Lionel]

Intel Support tells me that the bug has been fixed. They did not tell me when to expect the fix to appear in an update.

Hello, Mr. Steve.
Do you know if they've fixed this error?
I'm getting binary files written differently from how they are written by the same program on another older compiler (not Intel). Could that be the problem?

Thank you.

[Steve_Lionel]

My testing shows that the bug from this thread is fixed in the current release (ifort 2021.10.0, ifx 2023.2.0). I think this was an problem with INQUIRE and not the file itself. I doubt this is related to your issue.

[danikyr]

Thank you!
